gpui-terminal

A terminal emulator component for GPUI applications. Uses alacritty_terminal for VTE parsing.

Features

• Full ANSI escape sequence support
• 16 ANSI colors, 256-color mode, and 24-bit true color
• Bold, italic, and underline text styles
• Keyboard input with application cursor mode (vim/tmux compatible)
• Clipboard integration via OSC 52
• Dynamic configuration (font size, colors)
• Push-based async I/O
• Accepts any Read/Write streams (not tied to a specific PTY library)

Usage

use gpui_terminal::{TerminalConfig, TerminalView, ColorPalette};

// Create terminal with PTY reader/writer
let terminal = cx.new(|cx| {
    TerminalView::new(pty_writer, pty_reader, config, cx)
        .with_resize_callback(|cols, rows| {
            // Notify PTY of size change
        })
        .with_exit_callback(|_window, cx| {
            cx.quit();
        })
});

See src/main.rs for a complete example using portable-pty.

Configuration

let colors = ColorPalette::builder()
    .background(0x16, 0x16, 0x17)
    .foreground(0xC9, 0xC7, 0xCD)
    .cursor(0xC9, 0xC7, 0xCD)
    .black(0x10, 0x10, 0x10)
    // ... other colors
    .build();

let config = TerminalConfig {
    font_family: "Mononoki Nerd Font".into(),
    font_size: px(14.0),
    cols: 80,
    rows: 24,
    scrollback: 10000,
    line_height_multiplier: 1.05,
    padding: Edges::all(px(8.0)),
    colors,
};
